Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649212, here are decompositions:

109 + 8649103 = 8649212
151 + 8649061 = 8649212
163 + 8649049 = 8649212
211 + 8649001 = 8649212
283 + 8648929 = 8649212
331 + 8648881 = 8649212
349 + 8648863 = 8649212
373 + 8648839 = 8649212

Showing the first eight; more decompositions exist.
